FTP Server kurdum ama IP adresimden bağlanamıyorum sorunsalı

Single Port Forwarding  	 
   
  Port Forwarding can be used to set up public services on your network. When users from the Internet make certain requests on your network,  
  the Gateway can forward those requests to computers equipped to handle the requests. If, for example, you set the port number 80 (HTTP) to be 
   forwarded to IP Address 192.168.1.2, then all HTTP requests from outside users will be forwarded to 192.168.1.2. It is recommended that 
   the computer use static IP address. 
   
  You may use this function to establish a Web server or FTP server via an IP Gateway.  Be sure that you enter a valid IP Address. 
   (You may need to establish a static IP address with your ISP in order to properly run an Internet server.) For added security, 
   Internet users will be able to communicate with the server, but they will not actually be connected. The packets will simply be 
   forwarded through the Gateway. 
   
  To add a server using forwarding: 
   
     1. Enter an  Application name of the service you want to forward.  
     2. Enter the Ext.Port number. Check with your service application needed for External Port used. 
     3. Select the Protocol used by the services. 
     4. Enter the Int.Port number used by the application. 
     5. Enter the IP Address of the server that you want the Internet users to access.  
     6. Select Enable for that entry. 
     7. Click the Save Settings button to save the settings. 
   
  To delete a service entry: 
   
     1. Enter a zero number in the Ext.Port and Int. Port, and IP Address from the fields. 
     2. Uncheck the Enable check box. 
     3. Clear the Application field. 
     4. Click the Save Settings button to save any changes you make.
